Second hand dry heat sterilization cabinet pulsating vacuum sterilization machine

The core heat source is usually equipped with a stainless steel finned electric heater (power 9 kW~108 kW), installed in the air duct. Some large industrial equipment can use steam heating or gas infrared heating. Forced hot air circulation system: composed of a high-temperature resistant long shaft motor and a centrifugal fan. The fan blows cold air through the heating tube to become high-temperature hot air, which forms vertical or horizontal laminar flow in the sterilization room through the air duct, ensuring uniform temperature at all points inside the box (temperature difference ≤± 5 ℃)

Arrange the items to be sterilized (such as filled ampoules) neatly on a drying tray or mesh belt, and push them into the sterilization room. After closing the cabinet door, start the program and the circulating fan will suck in air and heat it up through the heater. High temperature dry and hot air circulates rapidly inside the box, penetrating the surface and pores of objects and transferring heat to microorganisms. Maintaining at 160 ℃~180 ℃ for a certain period of time (usually 1-2 hours), the proteins and nucleic acids in the microbial body undergo irreversible oxidative denaturation, thereby achieving the effects of sterilization and heat removal. After the program is completed, the items are naturally cooled at high temperatures or quickly cooled to a safe temperature by cold air before being taken out of the furnace to remove heat sources: dry heat not only kills nutrient cells, but also effectively destroys bacterial spores and endotoxins (heat sources), which is an effect that wet heat sterilization cannot achieve and is the gold standard for injection packaging sterilization. Environmental safety: No use of steam, chemical disinfectants (such as EO) or irradiation, non-toxic residue, friendly to the environment and operators. Specially suitable for sterilization of high temperature resistant, non moisture resistant items such as glass, metal, ceramics, as well as powdered drugs.
